WebApr 4, 2024 · Cardinality of power set is , where n is the number of elements in a set. Cartesian Products Let A and B be two sets. Cartesian product of A and B is denoted by A × B, is the set of all ordered pairs (a,b), where a belong to A and b belong to B. A × B = { (a, b) a ∈ A ∧ b ∈ B}. Example 1. What is Cartesian product of A = {1,2} and B = {p, q, r}.

Colin … Web(The cardinality of the power set of A). Now I know this is 2^n, and I remember seeing a sketch of why this was true. But the question occurred in a combinatorial context, so I thought about how to attack from a more combinatorial angle. I basically considered the cases of how many sets with cardinality 1, 2, 3, ..., up to n, that we could create.
